I think the first thing that you should do is take the baby to the doctor and get them a checkup to see if they are ok or not. Another thing that you should do is CALL 911.
That is the only thing that I can think of that you can do.
It is called high blood pressure
That is probably tongue sores. It should go away in some time... I hope that was what you were looking for! Feel better!
